Abstract
An improved adjustment mechanism for adjusting the maximum flow rate of conditioned air in an air distribution system controlled by a pneumatic control circuit. An air bladder controls the distribution of air, and the pressure is bled from the bladder under the control of a diaphragm against which pressure is fed back from the downstream side of the bladder. The control orifice through which the bladder pressure is exhausted is formed in the end of an exhaust tube that is axially adjustable. A cam and set screw arrangement provides a field adjustment for the exhaust tube to move the control orifice toward and away from the diaphragm for adjustment of the maximum flow rate. The cam has three point contact provided by a pair of feet and a second set screw which permits adjustment of the inclination of the cam surface. Rocking of the cam is prevented by a spring which counters the force applied to the cam by the first set screw.
